  30 ### How to flash
  31
  32 Unlike ordinary desktop boards, the BIOS version 3202 of ASUS P8C WS does not
  33 apply any write protection, so the main SPI flash can be accessed using
  34 [flashrom], and the whole flash is writable.
  35
  36 The following command may be used to flash coreboot. (To do so, linux kernel
  37 should be started with `iomem=relaxed`)
  38
  39 ```
  40 # flashrom -p internal -w coreboot.rom
  41 ```
  42
  43 The flash chip is a socketed DIP-8 SPI flash, so it's also easy to remove and
  44 flash externally.
